In the beginning, or right before that, there was no time. According to cosmologists, the universe started nearly fourteen billion years ago with a “big bang” and in an instant expanded to something closer to its current size, and it continues to expand faster than the speed of light. Before all that, though, there was nothing: no mass, no matter, no energy, no gravity, no motion, no change. No time.
